CHARLES A.' SOHIEREN, OF BROOKLYN, NEW YORK.

MACHINE-BELTING.

SPECIFICATION forming part of Letters Patent No. 380,222, dated March 27, 1888.

AApplication led January 28, 188B. Serial No. 262.245. (No model.)

To all whom it may concern,.-

Be it known that I, CHARLES A. SOHIEREN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State I 5 of New York, have invented certain new and 1Q appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a. part of this specification.

Myinvention relates to machine-belts.

The invention has a special application to sectional belts adapted for use on crowned pulleys, or, in other words, to belts composed of links or strips united by a series of pins and provided with longitudinal break-joints.

The improvement consists in applying to a belt of the above character the following construction and arrangement, which will first be fully set forth and described, and the points of novelty then indicated in the claim.

Figure l is a planV View of a section of a belt to which I have applied my improvements, portions of which are shown in section. Fig. 2 is an end view of the same.

The object of my improvement is to adapt a belt of this character so that a belt-shipper may be applied, to it for the purpose of shifting the belt from a loose to a fast pulley, or vice versa, or for shifting it under any other conditions, when the belt is in motion. Heretofore this has been impracticable in the construction ot' edge-laid longitudinal break-joint belts, for the reason that the pins have uniformly been riveted upon the outer edges of the belt in such position that they project beyond the edges thereof and .preclude the application thereto Aof a belt-shipper. To 0bviate this difficulty, and thereby render a belt of this character more universally applicable to the general belt trade, I have devised the means illustrated in the drawings and described herein.

The drawings represent a belt made of two longitudinal sections, a b, united by a breakjoint, c.

d represents the links, comprising both sections of the belt; but the belt may be made of edge laid strips, and it may have more than one break-joint at different points of the width of the belt.

e are the pins Which-unite the links or strips, which are preferably made of leather. The pins e have their heads countersunk into the outer links or strips, so that they may be perfectly flush with the outer edges of the belt, or sunk beneath the edges. The pins ejpass through the break-joint links c and are riveted upon them over washers f. In this manner the riveting is done within the belt and does not project beyond the outer edges, thereby interfering with the application of a belt-shipper.

'The break-joint links -here shown are flexible leather links havingvtheir convexities presented alternately in opposite directions;- but my invention may be applied to other forms of break-joint edge-laid belts-esuch, for instance. as are shown in Letters Patent Nos. 352,548, 370,237, and 370,238. j

Instead of riveting the pins, they may be screwed into threaded washers; or other fastenings may be employed known to the art.

I claim as my invention- The machine-belt herein described, composed of edge-laid strips or links and having a longitudinal joint therein which admits of lateral tiexure, in combination with a series of pins uniting the belt and longitudinal joint, said pins being countersunk along the outer edges of the belt and their projecting ends secured Within the belt along the longitudinal joint, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
